A device that changes linear motion into circular motion
How to convert rotational motion to linear motion (lego
An outer tube (10) with internal contours (10a), an inner shaft (11) with head (11a) with external contours (11b), an inner chamber (R) formed between tube (10) and shaft (11) and a plurality of roller elements (12) arranged in the inner chamber (R) and around the head (11a), which are in active engagement with at least one concentric ring (12). (12). When the system is actuated, the shaft (11) is surrounded by a tubular portion (14) that is arranged coaxially with respect to the central axis (a—a) of the shaft and moves translationally relative to the tube (10). This protects the system from external effects in a very simple way: (FIG. 2).
The present application claims precedence to German Patent Application 195 42 453, which was filed on November 14, 1995, and whose disclosure is made the subject matter of the present application.
Motion in a straight line: crash course physics #1
A mechanical system for converting linear motion to rotational motion comprises a strip of flexible material formed in a typically Z-shaped configuration, with the parts near the apexes of the Z remaining tangentially oriented during linear motion of the end sections, resulting in rotational motion of the central segment.

DEVICE FOR CONVERTING LINEAR MOTION TO ROTATIONAL MOTION INVENTOR. BY jw THE INVENTION’S Roots 1. The Invention’s Field A system for converting linear motion to rotational motion is the subject of this invention.
2. The Prior Art is Defined Motion transducers that convert linear motion to rotational motion have been around for a long time. When used in gauges, such transducers have the advantage of allowing for a wider scale range in the same or smaller area if the readout is rotary rather than linear. The well-known rack and pinion mechanism, which converts linear rack motion to rotary pinion motion, is one such system. On the pinion shaft, a needle or pointer may be positioned to rotate above a scale. Although such devices are ideal for low-accuracy work, their use in high-accuracy instruments is limited due to lost motion and frictional losses.

A reciprocating motion, also known as reciprocation, is a linear motion that repeats itself up and down or back and forth. It can be used in a variety of systems, such as reciprocating engines and pumps. Strokes are the two opposing movements that make up a single reciprocation loop. [requires citation]
In an internal combustion engine (a form of reciprocating engine), for example, the expansion of burning fuel in the cylinders periodically forces the piston down, turning the crankshaft via the connecting rod. The piston is pushed back up by the crankshaft’s continued rotation, ready for the next cycle. The piston moves in a reciprocating motion, which is transformed into circular motion by the crankshaft, which propels the vehicle or performs other useful tasks.

Young is the Third National Gunk of Rockford. There is a large amount of thrust at right angles to the direction of linear movement (side thrust) in nearly all known devices for changing circular motion to rectilinear motion, which causes appreciable wear in the reciprocating sections of the system. The cross block of a typical steam engine is probably the best known example of this side thrust and its accompanying wear.
Various eccentric type mechanisms have been used to transform circular motion to rectilinear motion, but these, too, suffer from side thrust issues and are unbalanced. As a result, they can only run at very low speeds.
As a result, a novel system for changing circular motion to rectilinear motion that removes substantially all side thrust is an object of the present invention. It is more precisely an object to build a system that consists of two members installed for relative rotational movement and antifriction bearing means between them in order to minimize side thrust to the point where it is absolutely eliminated for all practical purposes.
